My darkroom is tiny. I only use chemicals that are almost odorless. Citric acid stop bath was the first, then I started using odorless fixers. Here in Europe there is also Amaloco X89 and Moersch's ATS fixer.
But of course.... see my signature.
The future belongs to the few of us still willing to get our hands smell like fixing bath.
Since my darkroom is in my closet, I use Clayton odorless fixer and a water stop bath. Rodinal has a very slight smell, but not particularly notable. Especially since the space is small I have to keep strong smells to a minimum.
